The Phyla of Kingdom Monera

Bacteria are not easily classified. Lynn
Margulis and Karlene Schwartz
have proposed a division into 16 Phyla; the major ones are listed below:
| Phylum | Common Name | Number of Species |
| Archaebacteria | ||
| Omnibacteria | ||
| Cyanobacteria | ||
| Chloroxybacteria | ||
| Mycoplasmas, spiroplasma | ||
| Spirochaetes | ||
| Actinomycetes | ||
| Myxobacteria | ||
| Nitrogen fixing aerobes | ||
| Chemoautotrophs |
